I am not sure who put this seat here but it is very well done and is a magical place to sit and watch. There are many things to watch - ships coming/going, birds, the tide and maybe, if you are lucky, kite surfers. Of course it needs to be a nice day for you to want to linger here. On a wet or windy day this might not be such a good place to be.
Please take the time to rehide the cache from casual observation and it needs to be well tucked away to avoid being washed or blown away. With the beach so close, please look out for your children near the water.
